NTI RACKMUX KVM Drawer with UNIMUX Switch

INTRODUCTION

The RACKMUX-DS17-N(T)-xDVIHD is a KVM Drawer with USB KVM Switch (RACKMUX) that combines a rackmount 17” TFT/

LCD DVI monitor, SUN keyboard, trackball or touch pad mouse, and USB KVM switch (UNIMUX) in a space-saving 1RU industrial strength drawer. The RACKMUX is equipped with a built-in switch function, which allows control of up to sixteen DVI -enabled

USB computers with a single SUN keyboard, trackball or touchpad and DVI monitor. When access to a server rack is needed, the drawer can be pulled out and the display lifted up like a notebook computer, revealing the SUN keyboard and trackball or touchpad. When the drawer is not in use, the display can be folded forward and down so the 1RU drawer can be pushed into the cabinet easily and smoothly, helping to organize and streamline busy server rooms.

The onboard USB KVM switch allows access to any DVI-enabled Windows, MAC, or SUN USB CPUs from one DVI monitor, USB keyboard and USB mouse (up to 16 CPUs). Internal microprocessor circuitry allows all USB CPUs to be booted simultaneously without keyboard error. Port selection is accomplished through switches on the keyboard tray or keyboard commands.

INSTALLATION

Rack Mounting Instructions

The RACKMUX was designed to be mounted in a rack and includes mounting flanges to make attachment easy.

1. Determine the mounting height in the rack for the drawer. It should be a height comfortable to use the keyboard and see the

LCD display. Mark holes in each of the 4 corner cabinet rails at points all level with each other.

2. Secure the rear brackets to the rear rack cabinet rails. Apply the top screws (supplied) for each bracket to the holes marked in

step 1.

3. Lift the keyboard into position and line the studs on the left and right sides up with the slotted openings in the rear bracket.

Apply the nuts (supplied) to the studs but do not tighten the nuts yet.

FYI: There are 4 mounting studs provided on each side of the RACKMUX. Depending on the depth of the rack and distance apart of the cabinet rails, the position of the rear bracket may make all 4 studs available for use. In this case, apply the 2 nuts to the studs furthest apart from each other on each side.

4. Slide the drawer in until the top holes in the front bracket flanges line up with the holes marked in step 1. Secure the front brackets on the drawer to the front cabinet rails with two screws per bracket. Be sure to tighten the screws securely. Then tighten the nuts applied in step 3.

5. Apply one more screw to each of the rear brackets to complete the installation.

Power-Up Sequence

1. Using the key, unlock the drawer and slide the keyboard and LCD Display out far enough to raise the display to a comfortable viewing angle.

2. Power ON the RACKMUX with the power switch located on the rear of the drawer.

3. Power ON the monitor with the power switch located on the monitor.

4. Adjust the screen's brightness and contrast with the controls also located on the monitor– as needed.

5. Power ON any attached CPUs.

FYI: The CPUs can be powered at any time, although if a CPU needs a keyboard and/or mouse at power-ON, it should be powered after connecting to and powering-ON the RACKMUX.

6


USING THE UNIMUX

Once the RACKMUX is properly connected, the UNIMUX switch will enable a connection to be made between the attached CPUs and the monitor, keyboard, and mouse.

The UNIMUX can be controlled by three methods:

• front panel control using touch-switches and LEDs on the keyboard tray

• keyboard control through Command Mode

•

RS232 control (see page 10)

Front Panel Control

There is a panel of numbered touch-switches and LEDs on the keyboard tray of the RACKMUX. There is one switch and

LED for each CPU the switch will connect the monitor and input devices to. Pressing any touch-switch will connect the corresponding CPU to the monitor and input devices.

Holding down any touch-switch for more than 2 seconds will cause the UNIMUX to cycle through all modes of operation including COMMAND, BROADCAST, SCAN, and NORMAL (described in "Command Mode" below). The three MODE LEDs on the panel indicate which mode is selected. Release the touch-switch when the LEDs indicate the desired mode. When no mode

LEDs are illuminated the user is in Normal Mode controlling directly the CPU to which the user is connected through the UNIMUX.

Figure 6- CPU Select switches, status LEDs and Mode LEDs

Keyboard Control

Keyboard control of the UNIMUX switch is achieved using Command Mode - operated using the keyboard . By pressing

<Ctrl> + < ` > (accent/tilde key), the user can enter Command Mode. Once in Command Mode, typing a series of commands will cause the UNIMUX switch to connect the user to any one CPU connected to the switch. Pressing the <Esc> key will exit

Command Mode. The following instruction describes how to use the menus to operate the UNIMUX switch.

Command Mode

In order to control the UNIMUX with the keyboard connected, Command Mode must be enabled. To enter Command Mode from the keyboard:

Press

Ctrl

FYI: The user must exit Command Mode to type to a CPU.

To exit Command Mode, either hold down any touch-switch on the front panel for more than 2 seconds, OR press <ESC> on the keyboard.

Scan Mode

To activate Scan Mode press <S> while in Command Mode menu. When in Scan Mode the switch scans to each port with a CPU powered-ON. (The SCAN LED on the front panel will illuminate and remain ON while in Scan Mode. ) The port with the CPU powered-ON remains active while in use until it becomes idle for the configured dwell time (default time-out period is 5 seconds) before switching to the next powered-ON CPU port. See Command Mode section above for configuring the scan dwell time.

Note: The keyboard and mouse must remain idle for the full scan dwell time before the switch selects the next active port.

To begin scanning, press <Esc> to exit Command Mode.

To deactivate Scan Mode press <S> again while in Command Mode.

Broadcast Mode

To activate Broadcast Mode press <B> while in Command Mode. Broadcast Mode enables the user to type characters to all powered-ON CPUs simultaneously.

Note: The user must type somewhat slowly (less than 20 wpm) when in Broadcast Mode and cannot use the

<Backspace> key

.

To begin broadcasting, press <Esc> to exit Command Mode.

To deactivate Broadcast Mode press <B> again while in Command Mode.

Normal Mode

When the Broadcast, Scan, and Command LEDs are all OFF the user is in Normal Mode, controlling the CPU to which the user is connected through the UNIMUX.

8


No Sun Sleep Mode

Note: It is necessary to configure a Sun CPU (most versions) such that the Sleep Mode is not enabled. If the Sun CPU goes into Sleep Mode either automatically or manually, the user must reboot the Sun CPU in order to resume use of the

Sun CPU.

To disable the Sleep Mode, perform the following steps:

1. Select

2. Look for "Device Idle Time Before Power Saving Starts"

3. Select "Always ON"

4. Look for "Override Device Idle Time For:"

5. Make sure neither "Monitors" nor "Disks" are selected.

Select Country\Language Code

It is possible to configure the UNIMUX to emulate a specific international Sun keyboard regardless of what actual keyboard is connected. This is recommended when the CPU needs the layout code (i.e. a SUN CPU) and the keyboard doesn't have an explicit layout code (i.e. some Windows keyboards). To do this, manually set the UNIMUX to indicate the international keyboard identification number to the CPU using the following procedure;

1. Enter Command Mode

2. Type Lxx, where xx is the number from the list below that corresponds to the desired country code

3. Exit Command Mode

Note: If any SUN CPUs are connected to the UNIMUX, they must be rebooted. Keyboard configuration is only read by

SUN CPUs on startup.

RS232 CONTROL

RS232 enables the UNIMUX to be remotely controlled via RS232. To control the UNIMUX via RS232 the user has three options:

• write a program that runs on a PC using the Command Protocol (page 12)

• use the NTI Switch Control Program (page 14) provided on the CD

• use the SerTest program (page 14) provided on the CD

RS232 Connections and Configuration

Remote Connection

The RS232 Interface is designed to meet the RS232C standard and can be controlled from any CPU or other controller with an

RS232 communications port. The pin-out for the RJ45 connector on the unit is as follows:

Unit Address and Loop Back

To allow multiple units to be controlled from a single CPU serial port, the RS232 control interface is designed to allow "daisy chaining" up to 7 units. By setting the appropriate RS232 DIP switches, each unit can be given a unique address (1-7). Then the unit will only respond to commands on the bus if its address is embedded in the command. Use the following table to set the unit address.

DIP SWITCH

8 7 6 5

OFF

OFF

UNIT ADDRESS

OFF OFF OFF 0 (not valid)

OFF OFF ON 1 (default)

Note: The "loop back" RS232 DIP switch (RS232 DIP switch 1) should be ON for each unit in the chain.

OFF ON OFF OFF 4

OFF ON OFF ON 5

OFF ON ON OFF 6

OFF ON ON ON 7

Note: Pin 4 on the RS232 DIP switch is not used.

In order to connect multiple switches (up to 7) with RS232 connections to the same CPU, an NTI Matrix-Y-1 cable must be used.

Connect the Matrix-Y-1 cable (sold separately) between the RJ45-to-DB9 serial adapter (supplied) and the CPU as shown in

Fig. 9.

Command Protocol

RS232 commands supported by the unit are defined below. All command strings should be terminated with a <CR> (carriage return). When a command is sent, the entire string is echoed back along with a response from the addressed unit as shown in the command definitions. All characters in the command string should be upper case, and all numbers below 10 should have a leading 0 (ex: 1 = 01). As command strings are sent, the inner character delay cannot exceed 500 milliseconds.

Note: To use this command protocol, the user is required to write a program that will send an entire command string all at once, not character by character. Programs that send one character at a time (such as HyperTerminal) cannot be used to control the UNIMUX. Alternatively, the user may use the NTI Switch Control Program or SerTest to control the

UNIMUX via RS232 (see page 14).

If the first field is not a known command (as listed above) or SW field is different from the unit address programmed at the DIP switch (page 11), the command will be ignored. If the SW field corresponds to the unit address, but if the syntax is wrong after this field, the switch will answer with a bad response ?<CR>.

Syntax example:

CS 01,05,01<CR> (insert the space and commas as shown) which means “At the switch with unit address 01, connect CPU port 05 to user port 01”

The switch will answer with:

∗<CR>

Autostatus

When Autostatus is enabled, any output (user) -to-input (CPU) connection change in the UNIMUX will cause an Autostatus message to be sent via RS232 to the administrator. The format of the message would be "pc SW,OP:IP<CR>"

Example of an Autostatus message:

pc 01,01:04<CR> which means "At the switch with unit address 01, the output (User) (01) has changed connection to input (CPU) port 04."

Note: An Autostatus message to the administrator will be delayed by any RS232 traffic being received by the switch from the administrator.

By default, Autostatus is disabled and must be manually enabled.

Keyboard Configuration

The keyboard configuration of each CPU is saved in the UNIMUX switch. For example, if the CPU attached to Port 2 had CAPS

LOCK and NUM LOCK selected the last time that CPU was accessed, then they will automatically be set when that CPU is accessed again.

19


TROUBLESHOOTING

PROBLEM:

Keyboard Errors

SOLUTION:

Check cable connections on each CPU and the switch.

PROBLEM:

No Video

SOLUTION:

Check cable connections on each CPU and the switch. Verify that keyboard and video connect from each CPU to matching ports. After reconnecting, CPU may need to be re-booted in order to sense the monitor connection.

PROBLEM:

Keyboard/ Mouse does not work

SOLUTION:

UNIMUX may be in Command mode (NumLock, ScrollLock, and CapsLock LEDs are illuminated). Only

Command mode commands will be recognized while in Command mode. Press <Esc> to exit Command mode.

PROBLEM:

Scan or Broadcast does not work

SOLUTION:

After enabling the Scan or Broadcast mode, the user must exit Command mode for Scanning or Broadcasting to begin.

PROBLEM:

In Broadcast mode, the response is quite slow or some data gets lost

SOLUTION:

In Broadcast mode the data can only be entered at a rate of less than 20wpm. Try slowing down the typing rate.

PROBLEM:

No Video on RACKMUX LCD monitor

SOLUTION:

Make sure LCD monitor is in Digital mode, not PC mode. Adjust accordingly the OSD setting on LCD monitor

(See Setup Menu- page 18)
